Abstract
Now more and more interests are focused on carbon dioxide, a natural working fluid in energy systems. Flow and heat transfer performance of supercritical carbon dioxide are investigated in the present paper. The transient flow is calculated in a horizontal tube. The obtained results show an enhanced heat transfer is found when pressure is below 12MPa, comparing to water as working fluid. Furthermore, related natures are obtained and discussed in the paper.
